EXTINGUISHER FOR LAMP OR OIL-STOVE BURNERS.

SPECIFICATION forming part of Letters Patent No. 576,944, dated February9, 1897. Application filed February 2'7, 1895. Serial No. 539,910. (Nomodel.) Patented in England November 27, 1894,1lo. 23,028.

To all whom it may concern:

Be it known that 1, WILLIAM BRANDON, a subject of the Queen of GreatBritain, and a resident of Aston, near Birmingham, in the county ofWarwick, England, have invented certain new and useful Improvements inor Connected with Extinguishers for Lamp or Oil-Stove Burners, (forwhich British Letters Patent No. 23,023 were issued November 27, 1894,)of which the following is a specification.

The invention has for its object improvements in or connected with thatclass of extinguishers for lamp and oil-stove burners in which a pair ofhinged shutters or 'fiaps are employed; and the invention consists ofimproved a-nd simple means of mounting and operating such extinguishershutters or flaps so that they are normally held free of the burners,but are readily operated to extinguish the flame, as hereinafterdescribed and claimed.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan of a burner and extinguisher without its cone. Figs.2 and 3 are two end views showing the extinguisher out of action and inaction. Fig. 4 is a plan view. Fig. 5 is a cross-section of parts ontheline indicated, showing one of the stops at the ends of the burner tolimit the outward motion of the extinguisher flaps or shutters; and Fig.6 is a similar cross-section to that shown by Fig. 5 with the additionof the extinguisher flaps or shutters resting against the said stop.

In all the figures like parts are indicated by similar letters ofreference.

Referring to Figs. 1 and 2, a is the wicktube, and b the perforateddiaphragm, which may be of any ordinary character.

The extinguisher consists of apair of shutters or flaps e, the axes e ofwhich are each mounted in bearings 9 fixed to the diaphragm b, but nottouching the wick-tube a. Each axle c has a cranked end or arm 6 Iconnect to the ends of the arms a by means of yokes 6 a bow-spring e",which acts to keep the shutters or flaps e normally free of the flameand resting against the stops 9, which are fixed at the ends, but clearof the wick-tube a. By pressing together the ends of the spring 6 andconsequently the ends of the arms e the extinguisher shutters or flaps eare made to act, as shown at Fig. 3, and by liberating such parts theshutters or flaps e are by the action of the spring caused to return tothe position shown at Figs. 1, 2, and 6.

Having fully described my invention, what I desire to claim and secureby Letters Patent is- An extinguisher for lamp and oil stove burnerscomprising a wick-tube a, a perforated diaphragm b, bearings e fixed tothe diaphragm, contiguous to the wick-tube, the axes 6 having crank-armsc and flaps e, the single bow-string e the yokes e connecting the endsof the bow-spring with the crank arms, and the stops g; substantially asdescribed.

WILLIAM BRANDON. Witnesses:
